A machine screw has a recess in its body extending from the threaded end into the body. The recess intersects the threads. A tang slot extends across the end of the machine screw body. A locking member is in the recess and the tang of the locking member is in the tang slot. The locking member includes a spring which extends into the thread space so that, when the machine screw is screwed into a threaded part, the spring is deflected by the threaded part to releasably lock the machine screw in place.
